1.8t BAM Coolant Pipe Identification

Hi all,

can anyone please advise on where the 2 pipes are supposed to be connected to in this picture, one where I am popinting too and the other on the left hand side where the 4 way plastic coupler is. I have already identified the 2 pipes for the expansion tank, the 2 pipes for the heater matrix and everything else connects to either the top or bottom rad pipe runs in some way or another. I dont have any other open ports so I presume these are either directly linked to each other or there should be some other component like a secondary cooler ?



thanks

Further to above, i have found a diagram specific to the BAM, seems that I am missing hose 16 which has a partnumber 8L9 121 086K

this part number seems to be throwing up various different hoses when I look at the pictures. Can anyone with etka advise if there are any new numbers for this ?
